Stellaris 4.4.5 Pegasus Early Open Beta (c22e) Notes (25th June 2026)

Bugfix​

• Arkships now have a 10 year cooldown after benefiting from a Max Aura effect, meaning you can't chain them to get a level 10 ascension Arkship super early.
• Nomads can now build Megastructures in a system containing one of their Waystations even if the system has not been surveyed.
• Fixed that Tombworld Earth was spawning way too often, so often that it would spawn instead of the UNE when playing the GRS or CoM.
• Fixed an issue where pre-FTL earths couldn't have defensive armies (sorry this does not fix the issue of not having the cool unique armies :frowning2: )
• Assault Armies will no longer split into separate Transport Fleets after leaving the planet surface.
• Harvest Resources Contracts will now be cancelled if a different empire harvests the resources first.
• Fixed a very rare case where if you settled and left the event open for too long another empire could claim the system. The fix is delaying them from claiming the system for 300 days. Please make a decision before then.
• The CFL should no longer accept Orbital Rings as contestants (even though that’s why they call it a Championship Ring, right?)
• Added a fallback if your arkship was in a hyperjump when progressing through the adAkkaria event chains
• Due to legacy script your capital arkship was never able to find precursors
• Stopped Scan Debris Contract from auto-cancelling on accept
• Blocked the Sectors Map Mode for Nomads.
• Fixed habitats not using the correct entity from your chosen shipset.
• Fixed some scripted issues with refugee modifiers.
• Fixed issues with Payback and Broken Shackles district specializations.
• Fixed farming colony designation not applying to agri-drones.
• Bio-Repurposing tradition now provides the nomadic effects for nomadic necromancers instead of the necromancer effects.
• Brought the cost and upkeep of the Nanite Hub waystation module in line with the equivalent starbase building.
• Fixed the Realign Shields decision not recognising some pulsar systems.
• Living and Grid Amalgamated species now have bespoke living standards so they don't use consumer goods.
• Fixed Astro Harvester job modifiers not applying in some cases.
• Harvesting a celestial body that has no deposit no longer incurs a diplomatic opinion penalty.
• The Creativity Exhibition Vault now boosts Cruise Passengers for Forever Cruise empires, instead of applying its bonus to Bio-Trophies they do not have.
• Buildings that can be built on a planet or its orbital ring (Psi Corps, Planetary Shield Generator, Galactic Stock Exchange, Embassy, Noble Estates, Slave Processing Facility) can no longer be built as both a colony building and an Arkship starbase building at the same time.
• The Galactic Stock Exchange can no longer be built on both a planet and its orbital ring at the same time.
• Fixed pops sometimes being stuck in the Assimilation citizenship or stratum.
• Pops that already have the cybernetic or psionic trait are no longer flagged for assimilation they do not need.
• Negative arkship modifiers from Grand Refurbishment and Operational Checklist are removed when another empire conquers the arkship, so you aren't stuck with a bunch of negative modifiers and no way to remove them.
• Arkship can now issue a survey command by clicking the survey button and clicking on the system in galaxy map
• Fixed the tooltip information where the survey single planet vs surveying the whole system information was mixed up
• Fixed Waystations, Arkships and modded starbases that have forced components from starbase modules and buildings regressing their designs and losing components.
• If you are too slow and don't stop the Khan Aspirant from becoming the Khan they now properly despawn, avoiding a scenario where there are two Khans.
• If you play with 0 marauders enabled and as a Heirs of the Khan empire, then the backup Marauder empire will avoid Fallen Empire systems so that they don't get killed in the first few weeks, making you the Khan while others are still figuring out Blue Lasers.
• Fixed a crash when updating waystation networks
• Ranger Lodge now correctly informs that Biologists are converted into Rangers, instead of saying Rangers are converted into Rangers
• Arkship construction notification now mentions an arkship, not a starbase
• Missions counters can now be infinite
• Fixed missing localization for message descriptions
• Fixed the End-Bringers' shrouded world failing to spawn in games featuring Nomadic empires.
• Fixed Arkships unintentionally syncing to the same auto-generated design. Building or upgrading one Arkship will no longer sometimes overwrite armaments or utilities on others of the same type.
• Fleets that are repairing or upgrading now correctly sync their FTL, Jump Drive, and Catapult actions.
• Fixed an issue with generated empire adjectives.
• Inetian trader special project bound to planet, meaning that if your science ship were to blow up you can still progress
• The Claimant event's description received a scope fix
• "Secrets of the Past" event from "Biomorphosis" Ascension Situation blocked for Nomads
• Harvest Resources Contracts will now be cancelled if a different empire harvests the resources first.
• Nomads will no longer get double the benefit from their own resource producing megastructures. Megastructures will no longer be giving resources directly and a waystation will always be needed to collect those resources.
• Planets can now be bombarded during first contact war
• Contact view now properly closes if diplomacy window is opened
• Fixed some megastructure effects showing incorrect modifier icons and “+100%”.
• Rogue Servitors can no longer take a machine species as their secondary species when playing as a Forever Cruise. The machine can not be pampered.

AI​

• Fixed AI being disabled after a resync in MP.

UI/UX​

• The Operational Reserves situation now shows its capacity breakdown and stored/total readout in the Situation Log instead of an empty Finisher Effects panel.
• The Operational Reserves topbar tooltip now shows a predicted monthly change with per-resource Energy and Minerals contributions, each with a resource icon and coloured +/- value, and a Hold-ALT hint to expand the produced/consumed breakdown.
• When enabling nomads in empire creation, the civilian arkship is now selected by default.
• Arkships no longer show false clearable-blocker icons in the outliner.
• Fixed incorrect Arkship button texts in the planet view.
• Anomaly window now also shows the name of the anomaly

Performance​

• Fixed science ship Excavate and Astral Rift automation causing a recurring daily stutter when no reachable target was available.

Modding​

• Situations can define total_progress with per-stage section_weight for progress bars whose length and stage bands scale at runtime, with auto-generated _max_progress_add/_mult country modifiers and a situation_progress_percent trigger.
• Situations, stages, and approaches support custom_tooltip and custom_tooltip_with_modifiers (replacing the approach-only active_tooltip), and situations can override their Situation Log Active Effects and Finisher Effects panel titles and bodies.
• Added the orbital_ring_and_arkship_equivalent_absent scripted trigger.
• Starbase modules now also support `scripted_effect_cooldown`, `scripted_effect_cooldown_flag`, and `scripted_effect_cooldown_flag_desc`

We still have a number of changes coming to this branch, and will update the Open Beta next week. 4.4.5 is currently expected to release in about two weeks.
